BLOCK-MOLDING MACHINE.

Specification of Letters Patent.

Patented Dec. 24, 1907.

Application filed February '7, 1907. Serial No. 356,211.

To all whom it may concern:

Be it known that I, MILTON J. PALMITER, a citizen of the United States,residing at South Bend, in the county of St. Joseph and State ofIndiana, have invented certain new and useful Improvements inBlock-Molding Machines, of which the following is a specification.

This invention relates to block molding machines, and it has for anobject to provide a machine of this type which is inexpensive tomanufacture, simple in operation and durable in use.

With this and other objects in view the invention consists in the partsand combina tion of parts hereinafter described, illustrated in theaccompanying drawings and particularly pointed out in the appendedclaims.

In the drawings c-Fi ure 1 is aperspective view of the machine reac lyfor moldin Fig. 2 is a perspective view showing the ividin partitionwithdrawn and the front side wal lowered. 'Fig. 3 is a top view with thehopper or container removed. Fig. 4 is a view of the end of the machineopposite to that shown in the perspective views.

Referring more particularly to the drawings, 1 indicates a frameprovided with a hopper or container 2 for the loose material from whichthe blocks are to be made, the container or hopper having its bottomwall closed and its front wall open so that the material may be removedtherefrom and fed into the mold arranged below but in advance of thehopper or container.

The mold comprises a removable bottom or bed plate 3, a front side 4,hingedat 5 to the frame at its lower edge to swing forwardly, and aplurality of vertical partitions 6 connected at their rears by a backside 7. These vertical partitions or dividin plates 6 are arran ed toslide rearwardly off the bed plate an for this purpose a board 8 ispositioned in the rear of and in the plane of the bed plate 3.

To move the dividin plates to and from their position over the ed plate3, there is provided the following means. A rock shaft 9 is arran ed onthe front of the frame below the mold and has connected to one end anoperating lever 10. Also secured to said rock shaft 9 is a pair ofvertical arms 11 which are connected by links 12 with a pair of levers13 secured at their lower ends to an oscillatory shaft 14 which isarranged below the hopper 2. levers are connected by links 15 with therear side 7 of the mold.

The mold front side 4 is provided with a plurality of vertical grooves16 to receive the front ends of partitions 6, and is weighted at 17 sothat when released as hereinafter described, it will drop forwardly. Themold side is held up against the ends of the partitions by latches 18,pivoted to frame 1 and adapted to engage keepers 19 on opposite ends offront side. These latches are curved in such a manner that lugs 20, oneon the operating lever 10 and the other on a lever 21 secured tothat'end of shaft 9 opposite the operating lever, engages the latchesand move them to release the front side when the operating lever 10 ismoved to shift the partitions 6 rearwardly.

When the parts are in the position shown in Fig. 1 the mold units arefilled by material fed from hopper 2. After the usual tamping, the lever10 is moved rearwardly, causing lugs 20 to lift latches andthepartitions to be shifted to the rear. When the latches release thefront side it drops by gravity to the position shown in Fig. 2. Thebottom plate 3 with the blocks is then lifted and carried to a placewhere the blocks are dried, and another bottom plate is fitted to themachine. The front side is now lifted by hand and the lever 10 is movedforwardly carrying the partitions therewith and permitting the latchesto drop and lock the front side. The parts are again in position formolding.

It will be noted that I provide a means for operating the slidingpartitions, connected to the locking means of the front side to releasetllile latter and permit it to open automatica y.

Having thus described my invention, What I claim and desire to secure byLetters Patent is 1. A block molding machine comprising a bed plate,front and rear sides, the front side being hingedly mounted and movableout of operative position automatically and the rear side being slidableinto and out of operative position, a plurality of partitions connectedto the rear side and movable into and out of cooperative relation withthe hinged side, and means for moving the par-' At their upper endsthese.

operative position automatically, a plurality of partitions, lockingmeans for the hinged side, and means for moving the partitions,connected with the locking means to release the front side.

3. A block molding machine comprising a bed plate, a hinged front sidemovable to inoperative position automatically, a plurality of slidingpartitions, pivoted latches for holding the front side against movement,and means for moving the partitions, connected to the latches to releasethe front side.

4:. A block molding machine comprising a hopper open at its front; amold arranged below and in front of the hopper and formed of a bedplate, a hinged and weighted front side, a plurality of slidingpartitions, a back side connecting the partitions, and latches ,forholding the front side against the ends of the partitions: anoscillatory shaft arranged below the mold and connected to the slidingpartitions; and a pair of levers having means to engage the latches tooperate them.

5. A block molding machine, comprising a bed plate, a downwardlyswinging front side, latches for the front side, movable partitions forthe bed plate, an oscillatory shaft below the bed plate, levers on theshaft, adapted to operate the latches, and connection between the shaftand the movable partitions for moving the latter.

6. A block molding machine comprising a bed plate; a hinged front sidemovable to inoperative position automatically; a plurality ofpartitions;locking means for the hinged side; means for moving the partitions, and

means whereby the movement of the partitions out of operative positionwill effect a release of the aforesaid locking means of the front side.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
